CIIAUNOEY W. GAY, OF WEST SPRINGFIELD, MASSACHUSETTS.

PAPER-BOX MACHINE.

SPECIFICATION forming part of Letters Patent No. 741,324, dated October 13, 1903.

Application filed April 13, 1903.

T to whom it may concern:

Be it known that I, CHAUNOEY W. GAY, a

' citizen of the United States of America, and a resident of WestSpringfield, in the county of Hampden and State of Massachusetts, have invented certain new and useful Improvements in Paper-Bog; Machines, of which the following is a full, clear, and exact description.

This invention relates to improvementsin paper-box machines of the class in which ion-- gitudinally-scored blanks, of cardboard or other appropriate material, constituting the bodies of the boxes, (which are finally to have in this machine the form of a tubular carton with end flaps thereof left open and in the plane of the sides and ends of the box,) are placed in a pile upon a suitable support therefor, are fed forwardly at regular intervals one at a time,and brought while in flat condition after having received a marginal line of gum in transit to a place of support properly positioned relatively to means which restrain the intermediate portion of the blank and relatively to means which impart an overturning or folding action to the opposite side portions of the blank, so that such overturned portions are as to the marginal parts thereof superimposed one thereof on the other, to be stuck together by reason of thepreviouslyapplied adhesive, means preferably appertaining to the devices for overturning one of the side portions of the flap being operative in conjunction with a companion member for squeezing or pressing the adherent portions of the blank, and while the blank is held in the gripping pressure it is next, by the mechanism still retaining the grip thereon, carried to and discharged into the open end of a receiving-trough, whereat it is released by the means which had gripped and conveyed the now-formed carton thereto, and by being forced into the receiving'trough with a crowding pressure and against a yielding follower the successively-entered flattened tubular cartons are held under compression, insuring the setting of the gum or glue between their united overlapping faces, so that there may be no tendency of the cartons to spring or bulge open where intended to be stuck, and in conjunction with the receiving-troughinto which the cartons are brought'at'ter having Serial No. 152,455. (No model).

been gum med,folded,and united an automatic counting mechanism maybe employed, so

One motive for the production of the present improved carton-making machine is to provide a machine of such character as to the combination and arrangements of its respective devices which intimately operate on the blanks that adjustments within a considerable range are permitted, whereby the machine is readily available for various small runs of work which other descriptions of carton-making machines would not be readily adapted to, and the machine is especially adapted to fold and sticklongitudinally-scored carton-blanks irrespective of the shape or dimensions of the end flaps with which the blank may be provided.

Another object is to provide mechanism in the machine which in the overturning or folding operations enable such operations to be performed with strict precision on two of the longitudinal lines of scoring of the blank corresponding to or coincident with diagonally opposite corners of the set-up box; and the invention consists in the combinations and arrangements of devices and the constructions of certain of the devices, all substantially as hereinafter sufficiently described in conjunction with the accompanying drawings and covered in and by the claims.

The machine for making paper boxes or cartons organized and constructed in accordance with this invention is illustrated in the accompanying drawings, in which Figure 1 is an elevation of the machine as seen beyond the plane parallel with the line of infeeding of the blanks to the action of the folding mechanism. Figs. 2 and 3 together constitute a plan View, on a scale larger than that of Fig. 1, of the machine. The sectionline 1 1 on the plan indicates the plane in which certain of the parts shown in section in Fig. 1 are taken. Fig. 4 is a sectional elevation as taken on lined i, Fig. 3, the overturning or folding actions imparted on opposite side portions of the blank being here rendered manifest. Fig. 45* is a side elevation of a portion of the overturning device for one marginal part of the blank, shown in a position where it is previous to the overturning action. Fig. 5 is a sectional elevation as seen in the opposite direction from Fig. 4 and as indicated by the lines 5 5, Fig. 3, the parts which form the overturning of the blank being shown as having completed such operation. Fig. 6 is a view substantially similar to Fig. 5, but showing devices instrumental in forming part of the overturning operation as having moved to convey the carton in flattened tubular form to the receiver. the latter and the crowding device being represented in side elevation. Fig. '7 is a plan view of the receiving-trough and crowding device. Fig. 8 is a perspective View of the movable swords or restraining-blades for the blank and the overturning device for one side portion of the blank. Fig. 9 is a side elevation of a motionimparting device pertaining to the mechanism for infeeding the blank to the receivingtrough after having been folded and brought to such trough in carton form.

Similar characters of reference indicate corresponding parts in all of the views.'

In the drawings, A represents theframe of suitable open-work design to sustain the various supporting portions and movable devices of the machine, and B represents the main shaft shown as arranged to be driven by the pulley O and having mounted thereon cams to actuate the respective movable devices to be hereinafter referred to.

It will be here observed that the blanks or are piled up at the left-hand portion of the machine as Fig. 1 and the combined Figs-2 and 3 are viewed, these blanks being fed one at a time from the bottom of the pile while in a fiat condition horizontally onto the shelflike snpportsh and 1) b the latter being separated, as shown in Fig. 3, to give clear space between their ends for the operation or movement therebetween of the adjacent portions of one of the overturning devices, which has an oscillatory inovement'in a path across the plane of rest of the blank on its folding-support 1) b and the blanks coming onto these supports in relation to the restraining and overturning or folding devices are thereafter conveyed (having been folded and caused to assume the form of a flattened carton) in a direction at right angles to the infeed of the blanks to the receiving-trough and caused to have an enteringmovement thereinto. The blanks are scored previously to being piled within the adjustable gage-posts 20, which rise above the longitudinal slotted bases 22 for instance, as represented in the plan View, Fig.2and the forward middle portions of these blanks rest upon a comparatively narrow block or supporting member 23, while the rear portions of the blanks rest on the parallel horizontally-separated plates or sufficiently rigid strips 24 24, which are provided with the adjustable shoulder constituting blocks 25, confined by nuts and bolts in relation to the longitudinal slots 26 in such strips, these slots also-permitting, by the bolts 27 and nuts therefor, approaching or separating adjust-v ments of the strips on the transverse carrierbar 28, which has the slot 29 along its length, and said carrier-bar has longitudinally-bored hubs 30 at its ends, wherebyit has a guiding play on the horizontal studs 32, mounted on the brackets 33 of'the frame. The verticallyadjustable escapement-bar 34 regulates the outlet-opening for what become successively the bottom blanks of the pile, which blanks on the reciprocation of the strips 24, having the shoulders 25, are pushed in the proper direction of feed to and between the feed-rollers 35 35, which run them onto the aforementioned shelf-like supports 1) and b gage-stops 11 being provided at the leading ends of such supports.

The reciprocary movement of the carrier 28 for the shouldered strips 24 is imparted from a cam on the main shaft working against the thrust-rod 15, connected to the pivoted lever 16, which by the link 17 has pivotal connection with the carrier 28.

The feed-rolls 35 are geared together at one end of the arbors thereof, as indicated at 3'7, and one of the arbors is positively driven by the belt 38, running around the pulleys 39 and 40. One of the feed-rolls has an endwise portion 42 thereof in a line coincident with the flap or portion m of the blank which is to receive the line of gum or glue to enable it to be stuck after the blank is folded to the flap or portion relatively to which it is superimposed, there being preferablya groove 43 between the gumming portion of the roll and its body or feeding portion, whereby there will be a stoppage of any tendency of the adhesive to flow endwise along the roll. The arbors of the said feed-rolls, one of which has the gumming extension, are elongated beyond the bearings therefor in the frame and are adjustable therethrough, the adjustment being permitted by loosening the collars on,the arbors, the driving connection being detachably confined on said arbors, thereby adapting themselves to the axial adjustment. The

adjustment of the rolls enables the gumming extension to have its position corresponding to any desired feed-line of the portion of the blank to be gum med and enables the rolls to have such positions relatively to the general line of feed of the blank as to best adapt them for any particular work in progress.

The gum-box 44 is located and supported beneath the gumming portion 42 of the feedroll, it having a distributing-roll 45 therein carrying gum up therefrom onto the periphery of the aforementioned feed-roll part 42.

The aforementionedshelf-like supportingstrips 19 b are mounted on horizontal bars 46, slotted and held adjustably for closer-approached or more-separated relations, according to the widthof the blanks being worked, on a horizontal supporting-beam 47, which is slotted, and by the bolts and thumb-nuts 48, Fig. 6, permit the adjustments of the gage and support members I) b in the direction of the line of'infeed of the blanks, which is at right angles to the line ofthe adjustments which said gage-supports have toward and from each other. The guiding of the blanks from the feed-rolls 35 onto the said supports therefor is insured by a curved or inclined plate 50, Figs. 1 and 2, which prevent the sagging of the forward end of the blank, whereby it might not ride over the one of the upstanding members 52 52 of the aforementioned beam 47 which is adjacent the feedrolls.

A pair of blades or swords d (if, having a reciprocatory motion in a horizontal plane just above the level of the blank on the supports Z) I) and in theline of the infeed of the blanks, but having their range of motion at the opposite side of the blank-supports from the location of the supply-pile, are caused to assume their position seasonably over the blanks, these blades being adjusted as-to their separation by confining bolts and nuts 53 on the reciprocatory carrier 54 therefor, such carrier having the long slot 55. The blades are to have their outer edges so far separated as corresponds to a certain two of the longitudinal scorings of the blank and for serving as formers around which opposite outer portions of the blank are folded or overturned, so that the foldings will be exactly on the lines of scoring, whereby the corners of the carton will finally be true and square. A reciprocatory movement of the carrier-bar 54 for the swords d is imparted through the camactuated thrust-rod 56, which is pivotally connected to the intermediately-fulcrumed lever 57, the upper end of which, by link 58, has connection with the said carrier 54, and the support and guidance of the carrier is through means of its hollowend hub 59, running on the horizontal supporting rods 60, this mechanism being characteristically similar to the, shovel-feed motion aforementioned. The overturnings or foldings of the portions of the blank which in the flat extend oppositelybeyond the edges of the swords are accomplished by the operation of overturning devices which, as shown, are of specifically different characters, these devices working concurrently, however, to bring the blank from the fiat condition,a-s partially indicated in Fig. 4, to the relations indicated in Fig. 4 and finally to that represented in Fig. 5, and I will now describe the means for overturning what in the present illustrations is represented as the wider outlying portion a of the blank a.

Suitably below the position to which the wider portion 0, of the blank outlying beyond one of the swords is brought a revoluble bar f normally has its location, said bar, as represented in Fig. 8, being carried as a rigid extension and parallel witlrthe axis of an annular gear wheel 65, the hub 66 of which is journaled in the adjacent upstanding member 52 of the aforementioned supporting-beam 47, and the line of the horizontal barfis eccentric to the axis of its revoluble movement, coincident with the cent-er of the gear-wheel, and preferably the end portion 67 of the bar opposite from the place of its projection from the gear-wheel is deflected toward the axis of revolution and is pivotably connected at 68 in the upstanding lug 52 opposite from the one in which the gear-wheel hub is journaled. The motion of partial revolution of the bar f-as, for instance, from the position indicated in Fig. 6 and in dotted lines, Fig. 5, to the position represented by full lines in Fig. 5-is imparted by the reciprocatory movement of the rack-bar 68, the teeth of which mesh into the gear-wheel 65, the back-andt'orth motion to such bar being imparted primarily from a cam 69, Fig. 4, working against the rack-toothed thrust-bar 70, which meshes into the gear-wheel 72, having, with the radially-slotted arm 73 thereof, the adjustable connection of the connecting-rod 74, which is also adjustably connected with the longitudinally-slotted lever 75, suitablyfulcrumed, to the free end of which the rack-bar 68 is pivoted at 76. The gear-wheel 72, operated by the cam-actuating thrust-rod 70, is also instrumental in actuating the overturning device for the other portion a of the blank outlying beyond its adjacent sword oppositely from the normal extension of the blank portion ad, which last-mentioned device will be now described. This overturning device comprises a carrier 9 in the form of a lever fulcrumed on the rocking arbor 77, on which the aforementioned gear 72 is attached, said carrier-lever having a secondary lever h intermediately pivoted at 79 on an angular extension 80 of the carrier g, the portion 82 of such carrier being preferably widened to afford a sufficient bearing-surface under the blank and to receive the impact thereover of the widened portion 83 of the secondary lever h, which portion 83 is shown as being acute angular to the other portion, which is beyond its pivot. The carrier-lever g also has an extension 84, between which and the secondary lever h the spiral spring 85 is connected, said spring exerting the tendency to hold the inner straight member of the secondary lever toward the edge of the cam device 2' and to force the member 83 of the secondary lever toward the member 82 of the primary lever. The cam device 1' is held stationary as supported by the bracket 86, the same having at the curved working surface thereof with which the roller or stud 87 of the secondary lever h coacts a portion 88, which is concentric with the center of oscillation of the overturning device and non-effective to cause any swinging of the secondary lever relatively to the carrier-lever, a portion 89, which is decidedly prominent, whereby when the carrier is being swung in one direction the straight arm of the lever h will ride up thereon, as indicated in Figs 4 and 4, thereby insuring an increased distention of the member 83 and an opening thereof away from the carrier portion 82, and the said cam,furthermore, has located around at the portion of its edge beyond the dead portion 88 in the direction opposite the extreme 89 a slightly-expanded portion 90. The cam has within its side the facewise-opening groove '92, one margin of which is in circular continuation of the contour of the dead portion 88 of the cam, and a pawl 93, pivoted as shown in.Figs.4 and t and having its position of inclination between the most prominent portion 89 and the dead portion 88 of the cam, serves as a bridging continuation of the cam-surface at the end of and in the plane of the groove 92, being effective to cause the straight arm of the sec ondary lever to rideup onto the most prominent portion of the cam as the overturning device'is having its swinging movementleftward, as viewed in Figs. 4 and 4. The prominent portion 89 of the cam under or within which is the aforementioned groove 92 is of such partial length relatively to the path of movement of the coacting oscillatory devices that when the latter have reached the extreme of the leftward movement the working stud or roller 87 will have ridden down at the back end of the cam protuberance 89, so that on the reversed and rightward movement the part 87 instead of riding back up over the cam protuberance 89 has its transit through the groove, the cam relatively thereto for the greater portion of the reversed oscillatory motion being non-effective to force the member 83 away from the portion 82, although it will be perceived that as the cam portion 90 is reached by the lever roller-stud the lever has imparted thereto automaticallya degree of movement sufficient to open the part 83 from the part 82 for the release of the blank.

As shown in Figs. 5 and 6, the pawl-like cam continuing or bridging member 93 has on its affixed pivot which is journaled in the cam-body a little lever 95, to which a spring 96 has a reactive stress, so that the point of the inclined pawl member will normally be against the edge of the cam, and yet the rollerstud of the secondary lever on its retreating movement through the groove may click past the spring-pawl.

The scored blank brought onto the shelf like supports 17 b in the flat condition, the overturning device, comprising carrier 9 and secondary lever bodily movable concurrently therewith and having the swinging movements additional thereto and independently thereof, as described, have initially the relative position shown in Fig. 4c, the straightedged swords being projected in parallel lines over and closely to the face of the blank, with their outer edges coincident with two of the lines of scoring, and the revoluble barf havingat this time its position below the side portion of the blank opposite to the portion under which the overturning device 9 h has its location the operations of these devices are, as perceived in Fig; 4, to overturn the wide outlying portion a of the blank by the said revoluble bar f and to also overturn the gum portion a of the blank by the impingement thereagainst of the contacting jaw 83 of lever h thereagainst, and now while the bar I f remains stationary for a proper interval the roller-stud S7, riding down off of the highest hump 89 of the cam, insures the spring-retracted lever member 77. to have its jaw 83 exert a gripping action on the superimposed overturned portions and bottom layer of the blank, as represented in Fig. 5, so that on the reverse motion of the carrier g, whereby it moves from the position Fig. 5 to the position Fig. 6, the blank will be carried bodily to the open end of the receiving-trough j; but'just previous to such conveyance of the carton and in order that the bodily movement of the latter may not he obstructed by the swords around which the blank has been wrapped, as rendered manifest, the swords are carried endwise to the extreme of their motion, so that they are entirely withdrawn from within the carton, one sword having its thrust through the annular gear-wheel 65.

The troughj comprises opposite side boards 98 98 and base 99, having a recess 100 at its end, toward which the conveyer has its move ment, such recess being best seen in Figs. 3, 5, and '7, in which it is perceived that this centrally-formed recess is of less width than the width of the base-board of the trough, whereby opposite side ledges 102 102 are provided, onto which the lower edge of the carton comes to bearing at'a time about concurrent with the releasing of the gripping members of the carrier, which releasing, as pointed out, is cocasioned by the action of the slightly-expanded cam portion 90 relatively to the roller-stud of lever h. In Fig. 6 the gripping-jaws of the carrier device are shown as having the releasing separation above mentioned.

The device comprising parts 9 and h, operative as the overturner for one side portion of the blank and as the carrier for the carton, has working in conjunction therewith and properly tined pairs of infeeding-arms 105, mounted on rock-shafts 106 106, transversely of and above and below the open receiving end of the trough j, rocking movements being imparted to said shafts, whereby the infeeding-arms are out of the course of movement of the carton when the latter is being brought into the receiving-trough and whereby immediately thereafter such arms are swung from above and below against the rear side of the carton near its upper and lower edges to force it facewise along into the trough past the clicks or detents 107 107, which restrain it against tilting or falling facewise onto the trough from its edge-supported position, anda follower 108 isprovided in the trough, which backs against a member having a yielding resistance as the cartons are one after another brought into the trough, such yielding resistance imposing a pressure on the overlapped and stuck layers of the IIO cartons to insure the setting of the adhesive. The follower comprises an upstanding memher and a base member 109, to which a weighted cord is attached, an intermediate portion of such cord being guided by the sheave 112 from its horizontal course of draft on the follower in a direction toward the receiving end of the trough to its downward extension, at which the weight 113 is provided.

The rock-shaft carrying the lower pair of infeeding-arms 105 has rocking reciprocatory motion imparted thereto by the cam 114, Figs. 4 and 9, operating against the thrustrod 115, which is connected to the angular lever 116, having the pivotal mounting 117 at its elbow, while to the other arm of this angular lever, from which the rod is connected, a connecting-rod 118 is secured, such rod being also connected to a lever-arm 120, fixed to and extended angularly from the lower rock-shaft106. The upper rock-shaft, carrying the upper pair of infeeding-arms, has a radial fixed arm 121, linked bythe rod 122, so that the one system of cam-actuated devices or connections simultaneously and properly impart the back-and-forth swinging motions to the upper'and lower pairs of infeeders. The upper rock-shaft for the infeeders is journaled in the side brackets 123, which are-vertically adjustable on the side walls of the trough by reason of the slots 124 therein and the bolts 125, provided with confining-nuts, and the so journaled and adjustable rock-shaft is permitted to have its vertical movements of adjustment by the provision of slots 127 in the trough side wall.

The thrust-rod 115 has its connection with the angular lever 116 made an adjustable one by the provision of the slot 128 in the lever, at the margins of which the rod has a clamping bind, and a similar adjustable connection is made between the link-rod 122 and the lever-arm of the lower rock-shaft, so that the connections will not interfere with the elevation or the lowering of the upper infeeding device.

The upstanding side walls of the receivingtrough are adjustable toward and from each other while remaining in parallel planes by reason of the fact of their being made separately from the trough-base and having angular lugs 130, the bases of which have the slots 132, receiving through them the stems of the bolts 133, for which confiningnuts are provided for the clam ping bind. The base of the receiving trough has an attached do pending dovetail rib fitted in a dovetail way 135 of the supporting'bracket 186, and the usual automatic intermittently operating sidewise-shifting mechanism for the trough is provided substantially of the same character as common and well-known as the counter of envelop-machines, whereby the trough has slight hitching sidewise motions repeated twenty-five or other number of times to offset the cartons received in the trough in bunches of twenty-five or other predetermined number, as indicated in the plan view in Fig. 7.

The ratchetwheel 140, with which the properly-reciprocated pawl 142 coacts, the pick or working thrust of which pawl is regulated by the shield 143, has the face-cam 144, that crowds against the lug 145, which is as a part of the base of the trough, the trough having its sidewise movement, as cam-im pelled, gradually against the spring 146, which after the cam has completely rotated oppositely shifts the trough for the commencement of a new counting.
